Hoven wATnnnnATING ATTACHMENT ron.y RANGES.

To all 'whom t may concern: f

Beit known that we, JOSEPH EDWARD ZIM- MERMAN and JOHN ZIMMERMAN, both citizens of the United States, and residents, respectively, of the city of NewYork, Richmond Hill, and Glendale, borough of Queens,

in the county of Queens and State of New,

York, have invented a new and Improved House Tater-Heating Attachment for Ranges, of which the following is a full,

Among the objects of the present invention is to improve the special water back calculated for use in winter or cold weather for heat-ing water as a basis of a circulating system of house heating. We have found in practice that a device, such as indicated, ap-

plied to an ordinary cooking range in al dwelling house kitchen is well adapted for heating` an apartment or house suitable for an ordinary family. The object of the invention is to adapt a cooking range for ordinary house heating purposes through the instrumentality of a circulating system of water and yet not interfere with the ordinary function of the range for cooking, baking or other purpose such as the heating of the water in the adjacent kitchen boiler.

'l/Vith the foregoing and other objects in view the invention relates to certain novel features of construction hereinafter more fully set forth and claimed and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation or general view of a cooking range with our improve-A ment attached thereto. v

F ig. 2 is a plan view of the same, but, n-

dicating the top plates removed.

Fig. 3 is .a vertical longitudinal section onthe line 3-3 of Fig. 2.

Fig. 4 is a vertical transverse section on the line 4-4 of Fig. 1.

Fig. 5 is a det-ail perspective view of the water back of the circulating system which constitutes the principal part of our present improvement, parts of the same being broken away to show interior construction.

Fig. 6 is a vertical sectional view of the structure shown in Fig. `5.

Specification of Letters Patent. Patented Feb. 22, 1921. Application filed February 17, 1920. Serial No. 359,445.

Referring now more specifically to the drawings, we showour improvement as embodying a kitchen range 10, or its equivaconnection 17 with theuse of any approved y draft regulator, with .which per se at this` time we are not especially concerned.

The top of the range includes a plurality of detachable plates 18 and lids 19, the removal of which gives access directly to thev removable water back features to which our claim is drawn more directly.

As in the previous patent we employ a water back'2O (see- F ig. 4) at the front of .Y

the iire box having inlet and outletl connections 21 and 22 respectively, for communication with the kitchen boiler, not shown. Extending along the right end'of the range and e-specially along and in intimate association with the-fire box l2 and also across the rear end of the fire box at the back of the range is our improved water back 23, comprising an end wing 24 and a rear wing 25 in direct communication with each other, or constituting what may be said to be right. angular extensions ofeach other, said wings beingopen or yhollow with the cavities or .chambers therein extending all the way from the front end vcorner of theV fire 'box along the right end of the range, thence along the rear of the ire box terminating at the rear end corner of the baking oven. We wish to distinctly point out that the water backs 23 may be made any suitable size l' to conform to our design adapting them to be applied to any suitable make of range either now under construction or to be constructed, and furthermore that the water backs 23'are adapted to be inserted into place lining the two sides of the fire box, or removed therefrom `whenever desired and for any purpose, such as inter-change, repair, or for disconnection during the summer season. In some instances the water supply to the delivery pipes may be connected to the right end, or in otherinstallationssuch pipes may be connected at the rear, consequently we show an alternative connecting means at 26 and 27 for inlet and delivery connections respectively, along thev Vwing 24, and inlet and delivery connections vwings 2a and 25,

into the chamber 31.

' heated in the chambers 28 and 29 respectively, along the rear wing 25. Obviously the inlet connection in either adaptation is adjacent to the lower portion of the water back, while the delivery connection is adjacent to the top thereof, whereby the water heated inthe back will flow outward and upward along the delivery connection. The water back 23 is shown as divided substantially into four main horizontal chambers indicated at 30, 51, 32 andV 33 respectively, the several chambers being defined by certain partitions extending essen`` tially horizontally along the end and rear but with-passageways provided :tor the Vcirculation of the water upward from any chamber to the next above it. rthe lowermost chamber 30 is bounded at the top by means of apartition 34C extend` ing practically all the way along the water back, but having its ends terminating short,- of the ends of the back providing thereby passageways Se? through which the water may circulate from either separating the chambers 31 and 32, leads from theends ot the water rupted at a pointa about midway between'v the ends oit thechamber 3i whence the water 30 and 31 may pass upward into the chamber 32 along which it may pass in either direction toward the ends orn the chamber 32 and whence it will 'flow upward in turn through the openings 36 observedv at the ends of the partition 36 sepaV rating the chambers 32 and 33. Thus the water proceeding into the chamber 33 will be further heated therein and later iind its Y delivery -inally through the outlet 27 or 29.'

It will be noted that the inlet and outlet 26 and 27,- which are the preferred ones,"together with the partitions and their openings, are so arranged that 'the maximum d l gree of heating surface will be a'li'orded for the water passing from the inlet to the out let. In other words the irst partition above the inlet has its delivery into the next upper chamber as far as possible from the inlet, and the' next upper partition has its delivery into the next upper chamber as tar as possible from the preceding partition passageway. l

The upper wing which extends horizontally across the entire top ot the lire box, as well as over the top o the water baclr 20, is provided with nre holes 38 extending directly through said wing 37 for two important to provide direct directly over the intensity the heat tact with the water in the water back. further intensify the fire box, and secondly, er add to the surface con end oi chamber 30 l The partition 35,

bach, but is inter` 37V ot the water bach 23,

purposes; first, 2 heat tor cooking purposes To j. heating action on the water we provide a tubular bar 39 extending g, across the path of heat as it passes along is directed downward somewhat a large portion oi the heat is extracted prior to the reaching of the flue 17.

' in some instances we find it desirable to extend the pocket of the water back 23 to enlarge its capacity. This may be accomplished in various ways, but as shown we have provided a downwardly projecting flange or auxiliary wing 23a which extends throughout the full length of the end and rear wings, and constituting a pre-heater ior the water circulating through the water bach. The inlet 26 or 28 as the case may be, will in this event be transferred toa correspondinglylower position so that the cool- -est water will be admitted near the bottom edge of the water back in any case. The cavity or space within the extension 23 is Y preferably thinner or narrower as shown at 80 than the remaining chambers, although theouter walls ci the extension are preterfably flush with the corresponding walls of tthe wings directly'above, whereby the highfest heating eiiiciency and economy of space are realized, but practically all oi' the other features above enumerated are the same as set forth above.

lVe claim: 1. The combination with a heating appliance having a lire box and end and rear alls, oi' a house water heating device comrising a water back including end and rear hollow wings having direct connection with ich other, a vertical series of horizontal partitions extending from the inner to ,the uter walls of said wings, said partitions rovided with passage ways for the transfer I t water upwardly, said passageways ar- 'ranged in staggered relation, certain ot them eing at the ends of partitions, and others eing through partitions intermediate their ads, and inlet and outlet connections at the bottom and top respectively, of the end 2.
